Saving marine ecosystems is an important environmental issue that biologists and scientists are studying today. This issue is frequently debated and addressed by several government and nonprofit organizations due to its important impact on human health and well-being. Global warming has complicated the issue because it is causing the oceans to warm up and carbon to be absorbed by the oceans. Reckless and indiscriminate human activity has led to the pollution of the oceans and a decline in the populations of marine animals worldwide. As the apex predator, we need to make a change by conserving marine habitats and ecosystems throughout the world. The Marine Conservation Institute is already trying to create environmentally protected areas by safeguarding marine ecosystems on a global scale. Being eco friendly can also save you money. Doing so will limit further damage to the environment and protect marine ecosystems.
Marine conservation is the preservation and protection of all water ecosystems in this biosphere. Recently, illegal fishing and improper disposal of wastes have led to the seas being polluted with toxic chemicals; carcinogens, pesticides, herbicides, detergents, oils and plastic have all found their way into the seas and oceans due to indiscriminate dumping. Consequently, these toxins are leaching into our food chain. These toxins are both harmful to the health of a marine organism, and disruptive to the natural habitats of marine animals. Many species of marine animals like the Chinook salmon, Bottlenose dolphins, blue whales and the loggerhead turtle are slowly becoming endangered.
Global warming has further complicated the issue of marine conservation. Emissions from cars, factories and greenhouse gases have creat...

The Chesapeake Bay plays host to an astonishing amount of plant and animal life, providing much of our fish intake for species that aren’t being overfished. For the species that are being overdrawn, the Chesapeake Bay Foundation is working to restore the populations, and it’s going well thus far. Another theme that is endangering the marine life populations as well as the health of the human population is the massive amount of polluti...
As certain types of pollution damages our atmosphere, our natural protection from the sun weakens and as a result the Earth gets warmer with time, impacting the temperature of our seas. The unfortunate results of global warming and the co...
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship

What is the first marine mammal added to the endangered species list attributed primarily to climate change? As climate change melts the ice, it is projected that two thirds of polar bears will disappear by 2050. This drastic decline in the polar bear is occurring in our lifetime, which is but a miniscule fraction of the time polar bears have explored the vast Arctic seas (National Wildlife Federation, 2014).
During the 20th century both air and sea temperature has increased and causing several problems. The increase in temperature has caused damages to our eco system. In some countries temperature has increased by a few degrees. In winter, in places where it was cold, now the temperatures has increased and even the sea temperatures have increased, which is melting the Iceberg and destroying the marine life. Scientists projected that if emissions of heat-trapping carbon emission aren’t reduced, average surface temperature could increased 3 to 10 degrees Fahrenheit by the end the century. A good example is that in some Europeans countries the...
Some studies have found “that atmospheric CO2 concentration is approximately 383 parts per million by volume (ppmv), a level not seen in at least 650,000 years, and it is projected to increase by 0.5% per year throughout the 21st century.” (Guinotte) “This is because…the ocean absorbs about a third of fossil fuel emissions, but this amount is likely to increase to 90% in the future.” (Bralower) As a result, “the chemistry of the world's oceans is changing at a rate not seen for 65 million years, with far-reaching implications for marine biodiversity and food security, according to a new United Nations study...” (Knight) “…This change is cause for serious concern [for] many marine organisms…, [because they] may not be able to adapt quickly enough to survive these changes.” (Guinotte)

...hrow off the balance of the ecosystem. Different marine biodiversity requires different types of ways to conserve them, some need government and some do not. Depending on the different types of technology of public goods supplied, there are different ways to and different methods to preserve the marine biodiversity. We have looked at the different types of externalities that are associated with impure public goods (in this case marine biodiversity). We also looked at the three types of technology of public good supplies and see why it affects marine biodiversity. Lastly, we have discussed the incentives to conserve marine biodiversity, both private solutions and public solutions. To put it briefly, “wildlife exploitation and conservation involves various costs and benefits, which should all be taken into account to achieve an optimal outcome.” (Bulte, 1)
Water pollution has had devastating effects on the environment, which include irreversible effects to the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousand of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever; unless there is a balance. We must protect the resources we have in order for them to last into the next generation. Every time we throw away a plastic bottle, drive our cars, and even burn those millions of fossil fuels to operate all those huge factories, there is a chance it will pollute the ocean and eventually effect the way we live. There should be stricter laws regulating human pollution, in order to protect our oceans ecosystem.

With guidance from Edgar’s research, future MPAs should be designed to incorporate the five key features discussed, and in relation to these factors additional consideration should be given to the future activities that may influence an MPA’s effectiveness, for example future marine uses such as alternative forms of energy. This is where the Halpern’s suggestion to focus more on ecosystem-based management approaches may present a possible means to do so, as this approach addresses the wider-scope issues that will impact the world’s oceans on a global scale and may help limit effects, outside the boundaries of MPAs, that could potentially shape and alter the ability of an MPA to achieve its conservation goals.
The coral reefs of the world need our help now. You do not have to be a marine biologist to have an effect on the reefs around the world. By simply conserving water, you can help limit the water runoff into the oceans. Limit the amount of emissions put off by vehicles by carpooling or taking a bus. Even though we may live thousands of miles away from a coral reef, we must use caution when adding chemicals to our lawns. Planting a tree not only reduces the amount of water runoff; it also lowers the earth’s temperature. Something as simple as spreading the word can have major
Research from the University of California San Diego Scripps Institution of Oceanography said that species in the ocean consume a projected 12,000 to 24,000 tons of plastic every year in the Pacific Ocean (Nall, 2014). Pollution of recyclable materials in the oceans is one of the leading causes of why some marine species are nearing extinction. Many authors of articles and books analyzing this topic tend to agree that pollution of our oceans is a problem. The future of this problem is where their ideas tend to differ. The following four literature reviews attempt to demonstrate and support my belief that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there are things that we as humans can do to change this. Imagine a world where we didn’t have to constantly worry about the vicious cycle of humans affecting animals and then animals in turn affecting us through consumption.
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
